UNITED STATES PATENT OFFICE GEORGE P. REED, OF ROXBURY, MASSACHUSETTS.

IMPROVEMENTIN WATCH-REGULATORS.

Specification forming part of Letters Patent No. 49,154, dated August 1,1865.

To all whom it may concern.-

Be it known that I, GEORGE P. REED, of Roxbury, in the county of Norfolkand State of Massachusetts, have invented an Improved Regulator forWatches or Ohronometers; and I do hereby declare the same to be fullydescribed in the following; specification, and represented in theaccompanying drawings, of which Figure l is a top view, and Fig. 2 anend elevation of it.

The nature of my invention consists in the application of a spring andan adjusting-screw, or their equivalents, to the pointer or handle. ofthe regulator and to the pins which embrace the hair-spring, the wholebeing substantially as hereinafter explained.

In the regulation of watches with the ordinary regulator, a considerabledifticulty is ottenexperiencedin moving the pointerorhandle to the exactposition for the watch to run with true time. The difficulty is toimpart to it a sufliciently small degree of motion. The manner in whichI obviate this may be described.

In the common regulator the pins or studs extend down from its pointerand on opposite sides of the h2liF-S1TH'IIlg. It is the movement of thepointer or the studs on the spring by the pointer that effects thevibration or action of the hair-spring of the balance. Instead ofprojecting these pins from the pointer, I fasten to the said pointer b acurved spring, 0, ar-

ranged concentricallywith and so as to circumscribe the ring (l of thepointer, and I extend the two pins gg downward from the said spring 0,near to its free extremity, and so as to embrace the hair-spring h,which is fastened in the ordinary manner at 0. Next I screw a screw, f,through the pointer and against the spring near its free end, the wholebeing arranged as shown in the drawings.

The manner of using this regulator may be thus described. After thehandle or pointer may have been adjusted on that division of thegraduated are or scale a which maybe nearest to the postion for the trueadjustment we have only to produce the necessary subsequent change ofposition of the pins by either screwinguporunscrewingtheadjusting-screw,so as to vary the distance of the end of the spring from the pointer. Inthis way very excellent regulation can be obtained.

What I claim as my invention is-- The application of the curved spring aand its adjusting-screw f to the pointer Z), in combination with theapplication of the hair-spring,

pins, or studs to the said spring 0, the whole being substantially asand for the purpose as explained.
